A kind of seedling-raising substrate of huangzhirunnan and a method of raising seedlings using the substrate

Abstract

Provided is a seedling cultivation medium of machilus versicolora. The medium is put in a non-woven fabric container bag, and comprises peat, coconut powders, perlite, and organic fertilizer. The ratio of the peat, the coconut powders, and the perlite by mass fraction is 3:2:1, content of the organic fertilizer is 15 g / L, pH value of the medium is 5.3 to 6.5, medium EC value is 1-1.5 mS / cm, and total porosity of the medium is 60-85%. The seedling cultivation method using the seedling cultivation medium comprises germination accelerating, hill-seeding, fertilizer constituent management, root cutting, seedling hardening, and subsequent management. Using light seedling cultivation medium and the non-woven fabric container bag thereof, and combining with the seedling cultivation method of firstly accelerating germination and cutting roots and then sowing in a spaced manner in the container are beneficial for culturing high-quality seedlings whose side roots are developed, and can prevent the roots from being damaged when the seedlings are lifted. Using the container-grown seedlings cultured by the seedling cultivation medium of machilus versicolora and the seedling cultivation method to afforest, afforestation survival rate reaches up to more than 90%.

Description

technical field

[0001] The invention relates to a seedling-raising substrate and a seedling-raising method thereof, in particular to a seedling-raising substrate and a seedling-raising method using the substrate. Background technique

[0002] Huangzhi Runnan ( Machilus versicolora ), is an evergreen tree of the genus Runnan in the Lauraceae family. It is a new species discovered in recent years. Its material is not warped or cracked, has a fragrance, and has a tiger spot pattern. It is bright and clean, comparable to Phoebe. It is suitable for making boards, or peeling them as veneer materials for boards for furniture and construction. It is a precious timber tree species with high economic value. However, due to its specific environmental requirements, it is difficult to regenerate naturally. It is often associated with mid-subtropical evergreen broad-leaved forests, and rarely forms a constitutive species distributed in patches. It has been found through research that Ph...
